In October last year, AMD released its second-generation Radeon HD 6800 DirectX 11 architecture, codenamed Northern Islands. The time spent between HD 5000 and HD 6000 was used to refine and fine-tune its architecture to better suit the existing 40 nm silicon fabrication process, by promising to churn out higher performance per Watt and performance per mm² of die-area (plays an important role in product pricing), compared to the previous-generation Evergreen architecture.
With the HIS HD 6850 IceQ X Turbo, the company is introducing a new heatsink design. The IceQ X cooler uses blue transparent plastic to convey an image of "frozen iceblock" to the user. "Turbo" in the name stands for higher clocks out of the box, which are well increased compared to the AMD reference design.

You will receive:
- Graphics card
- Driver CD + Documentation
- DVI Adapter
- CrossFire Bridge
- PCI-Express Power Cable
The cooler uses a light blue transparent plastic shroud which does not feel flimsy at all.
The card requires two slots in your system.
As output configuration you will find two DVI ports, one full-size DisplayPort and one full-size HDMI port. AMD's display output logic is clearly superior to what NVIDIA has to offer at this time. Vendors are free to combine six TMDS links into any output configuration they want (dual-link DVI consuming two links) - and use them all at the same time. AMD has also introduced DisplayPort 1.2 support with their new cards which allows the use of a DisplayPort hub to connect multiple monitors, or daisy chain them together.
An HDMI sound device is also included in the GPU. The HDMI interface is HDMI 1.4a compatible which includes Dolby TrueHD, DTS-HD, AC-3, DTS and up to 7.1 channel audio with 192 kHz / 24-bit output. The new revision also brings support for Blu-ray 3D movies which will become important later this year when we will see first Blu-ray 3D titles shipping.
You may combine up to two HD 6800 cards of any model from any vendor in CrossFire.
